Add your 2 chopped onions and 20ml of your vegetable oil to your blender and blitz until your onions are a smooth puree
Heat the rest of your oil (80ml) in your pan and add your onion puree. Stir it a little then leave it on the lowest heat to turn golden. It will take about 5 minutes but keep an eye on it so it doesn't burn
Whilst your onions are caramelising add the rest of your ingredients to your blender (you don't need to rinse it) and blitz until you have a smooth sauce
When your onions have turned a nice golden brown (see the video below) give them a stir then add your tomato sauce. Give everything a good mix then leave it to simmer on the lowest heat for 20 minutes. Make sure to stir your sauce every 5 minutes when the oil rises to the top. This is to stop your sauce sticking to the bottom of your pan
Add your 2 1/2 cups of rinsed basmati rice to your stew and stir it in well so all your rice grains are covered
Add in 2 1/2 cups of water and stir everything well. Then cover your pan with some foil and then the pan lid and leave it to simmer on a low heat for 30 minutes
When your rice is cooked fluff it up with a fork
Now it's time to enjoy, so dig in (",)

Notes
You can substitute dried chilli for fresh chillies or Ghanaian Shito
You can use fresh ginger instead of ground ginger
Remember to taste your sauce before you add it to your golden onions and adjust the flavours to your liking
